![]() You easily might have a slight leak definitely - but that could also be unrelated to your overheat situation. White residue can be early signs of a small leak, (so yeah you probably do have some kind of small leak) but you don't indicate any notable coolant loss at the tank so that can't really be your overheat cause. I also noticed the white specs around the expansion tank, one of the hoses, and part of the fan.When you say 'belly pan' do you mean 'valley pan'? Upon further inspection, I noticed a small coolant leak. Any ideas? I know E39s can be notorious for cooling system issues, but I'm not sure if it's one thing or possibly multiple things. A few hours later, I started it up again in my driveway and let it idle for a while and the temp was fine. The temperature went back down to normal and remained normal for a few miles until I got home. I pulled over, shut the car off for a few minutes, started up again and drove off. Earlier today, it spiked and I got the "coolant temperature" warning, which I never got before. But I've noticed more recently that the temp gauge has started fluctuating it increases gradually toward the red and goes back down again after a minute or so. I have checked it periodically, to always find that there is plenty of coolant in the reservoir and the float is where it should be. For quite a while, I've been getting the "check coolant level" message. A quick trip to a qualified mechanic with a diagnostic computer will tell you if the check engine light has anything to do with a coolant temperature sensor or not.So I've been having an intermittent issue with the cooling system in my 540i. In many vehicles, a faulty coolant temperature system will trigger a check engine light or service engine light on your 2018 Jeep Compass 's dashboard. This can possibly happen when the coolant is leaking, causing the temperature sensor to behave erratically. If everything else is in order, failure in this test should be because of a faulty coolant temperature sensor.Īnother telltale sign of your coolant temperature sensor not functioning properly is if your engine is overheating frequently. To confirm, you could run your 2018 Jeep Compass through an emissions test. If you start having trouble starting your 2018 Jeep Compass after it has reached its normal operating temperature, this is usually a very good sign that you need to have the coolant temperature sensor checked. If your 2018 Jeep Compass starts to use a lot more gasoline than usual, or black smoke is starting to come from the exhaust pipe, these are indicators that the coolant temperature sensor in your 2018 Jeep Compass could be defective, and needs to be replaced. Symptoms of a Bad Coolant Temperature Sensor If there are two sensors, one of them is the coolant temperature sensor while the other is more correctly called the coolant temperature sending unit, which sends information from the control unit to the dashboard of the2018 Jeep Compass ![]() However, some vehicles dispense with the need for two temperature sensors by using just one sensor to do both tasks. There may be two temperature sensors in some vehicles, one to send information from the engine system to the control unit and another from the control unit to the dashboard. However, it is usually in close proximity of the thermostat of the cooling system, or inside it. Where to Find the Coolant Temperature Sensorĭifferent 2018 Jeep Compass manufacturers install the coolant temperature sensor differently. By this continuous monitoring of coolant resistance (and the voltage output), the coolant temperature sensor sends temperature information to the2018 Jeep Compass s engine control unit. This voltage output is sent to the electronic control unit of the vehicle, which constantly measures the resistance across the2018 Jeep Compass s coolant. As the temperature rises, the resistance of the2018 Jeep Compass s coolant drops and this in turn decreases the potential difference output. The temperature of a thermistor influences its resistance in an inverse proportion. Thus, principally, the coolant temperature sensor is a thermistor. As the temperature of the engine changes, the potential difference output of the device also changes, and this can be measured by the engine's control unit. This device works on the principle of dependence of potential difference in temperature. The Coolant Temperature Sensor's Function , abbreviated as CTS, in your 2018 Jeep Compass is an important device that enables the control unit to give alerts if the engine is overheating or if the temperature within the system is rising for some reason.
